Specialized cells of the dermal system in plants that function in gas exchange are called stomata.

The little apertures known as stomata are found on the epidermis of leaves. Stomata are visible under a light microscope. Stomata can be found on the stems and other portions of various plants. In gaseous exchange and photosynthesis, stomata are crucial. Through opening and closing, they regulate the rate of transpiration.

The stomata are made up of tiny pores termed stoma that are encircled by two guard cells. The turgidity of guard cells determines how frequently stomata open and close. The pore's surrounding cell wall is resilient and adaptable. Both monocots and dicots typically have different guard cell shapes, but the mechanism is the same in both. Guard cells have chloroplasts and are shaped like beans. They absorb light and have chlorophyll in them.

Hence, stomata cell plays role in gaseous exchange.

A similarity between PCR and DNA replication would be that both are chain processes that polymerize.

They also move along each strand in the 5′ to 3′ direction. Due to their antiparallel orientation, the two DNA strands polymerize in opposing directions. Enzymes that polymerize DNA also carry out both processes.DNA replication and PCR have a number of characteristics. Both are methods for creating DNA. Both are polymerizing chain reactions that move along each strand in the 5′ to 3′ direction. Double-stranded DNA has split apart during both procedures.

PCR needs a DNA polymerase enzyme, which creates new DNA strands by utilizing existing strands as templates, much like DNA replication in an organism. Taq polymerase is the best choice for PCR due to its thermal stability. As will be demonstrated, the template DNA is repeatedly denatured at high temperatures.

p16 is a tumour suppressor protein that functions as a cyclin-dependent kinase inhibitor and is required for cell cycle regulation. Because p16 inhibits cyclin-dependent kinases that phosphorylate Rb, it can slow down the cell cycle.

Tumor suppressor genes, also known as anti-oncogenes, encode proteins that transduce negative cell growth regulatory signals such cell cycle arrest and death.

The TP53 gene codes for the production of a protein known as tumour protein p53 (or p53). This protein functions as a tumour suppressor, which means it controls cell division by preventing cells from growing and dividing (proliferating) too quickly or uncontrollably.

Correct answer: letter D) sarcomere

This is the basic unit of contraction and relaxation within the muscle fiber. The sarcomere is formed by protein filaments (actin and myosin) that slide over each other, generating force and causing muscle contraction.

One of the most important components of muscle fibers is the sarcomere, which is responsible for the contraction and relaxation of muscle fibers and is the fundamental unit of muscle contraction.

The sarcomere is made up of two types of protein filaments: actin and myosin. These two proteins are arranged in an overlapping pattern, with actin forming a thin filament and myosin forming a thick filament. When the sarcomere contracts, the proteins slide over each other, generating force and causing the fibers to shorten and produce a muscle contraction.

Energy is extracted from fossil fuels by combustion (burning). Despite the presence of impurities in fossil fuels, hydrocarbon combustion is the predominant process in the combustion of fossil fuels.

The energy required to break the bonds in hydrocarbon molecules is far less than the energy generated during bond formation in CO2 and H2O molecules.

Both asexual and sexual reproduction are options for anemones, and each has advantages and drawbacks of its own. Asexual reproduction produces children who are genetically identical to their parents. Compared to sexual reproduction, asexual reproduction enables the development of higher numbers of unique progeny more quickly and with less energy consumption; in stable marine conditions, this is a dependable, efficient, and successful method of reproduction.

DNA

Explanation:

The statement, "A DNA fragment with 100 base pairs is smaller than a DNA fragment with 150 base pairs," is true.

DNA is composed of two strands of nucleotides, each of which contains four different types of nucleotides. These nucleotides, called adenine (A), cytosine (C), guanine (G), and thymine (T), are held together by hydrogen bonds, forming base pairs. The length of a DNA fragment is determined by the number of base pairs it contains, and therefore a DNA fragment with 100 base pairs will be shorter than a DNA fragment with 150 base pairs.

The length of a DNA fragment is important because it determines the amount of information it contains. For example, a DNA fragment with 100 base pairs will contain less information than a fragment with 150 base pairs. In addition, the length of a DNA fragment also affects its ability to interact with other molecules. For example, a fragment with 100 base pairs may be unable to interact with certain enzymes or proteins that require a longer fragment.
